URL Shortener Tester

This application continuously sends POST requests to a URL shortener service at http://localhost:8080/shorten with random data. It tracks failed requests and stops when the number of failed requests reaches 10 or the total number of requests sent reaches 10 million. Additionally, it sends override requests to http://localhost:8080/admin/override/:shortcode for 20% of the future-dated successful requests from each batch.

Assumptions

• The target URL for the URL shortener service is http://localhost:8080/shorten.
• The target URL for the override service is http://localhost:8080/admin/override/:shortcode.
• The API key for authentication is your_user_key.
• The admin key for override requests is your_admin_key.

How It Works

1. The application generates random request data, including a long_url and a release_date.
2. It sends POST requests in batches of 100 per runner to the URL shortener service. It runs 5 concurrent runners by default.
3. If a request fails, the request data is stored in a map of failed requests.
4. The application prints the details of failed requests and the total number of requests sent after each batch.
5. The application waits for 2 seconds before sending the next batch.
6. The application selects 20% of the future-dated successful requests from each batch and sends override requests to the override service.
7. The loop continues for each runner until the number of failed requests reaches 10 or the total number of requests sent reaches 10 million.

Usage

1. Ensure that the URL shortener service is running at http://localhost:8080/shorten.
2. Ensure that the override service is running at http://localhost:8080/admin/override/:shortcode.
3. Update the userKey and adminKey variables in main.go with your actual keys if different from your_user_key and your_admin_key.
4. Run the application go run main.go
